Help – Saab down – V-belt off – engine possibly broken?

with the request for help: was on the highway and at once the warning light for the battery went on and the steering was heavier. later the radio went off, the heat indicator went up and the tacho played crazy, also the abs light and the brake light went on. so I drove still a few kilometers until I finally lay down the lights were meanwhile also off and at the end twitched twice the engine light on. the workshop says, V-belt is not meh r there and the suspension is broken / missing too. also the climate compressor has broken. the calculation is already over 1000 euro and it is not clear whether the engine is also broken. I don’t know if I should give the order. who knows if the engine has also broken or if other parts can be affected. it is worth doing it again. saab 9.3 cabrio turbocharger bj99 model2000 many thanks to lisa
